The composition of electricity production has drastically changed over the past few years. After recognizing the environmental impacts of conventional fossil fuel power plants, the Hungarian state also aim climate protection goals, opening a new chapter in the history of Hungary’s energy production, which based on nuclear and fossil fuel power plants. In the past few years, support for renewable energy plants has been implemented on the basis of the KÁT (Mandatory Transfer System), while at present the METAR (Renewable Support System) replaces the KÁT system. The KÁT entitlements which were required in 2016 can be used until the end of 2018. According to the old regulations, anyone could apply for a KÁT license, so in 2016 more than 2000 MW solar power capacity (equivalent to Paks 1's installed capacity) licence were out given. Those who claimed KÁT privileges were typically traded with the privilege, because they were not restricted either by the pretender nor by the territory. From the former sentence, the reader can already guess, that in two and a half years, only a tenth of the out given capacity was established. The METAR system has more stringent regulations and shorter support time, therefore the KÁT power plant can be set up under more favorable conditions. According to the government's new view, farmers should invest in solar parks on outdoor land sites. At the beginning of 2018, the government made a decision that it should not be allowed to trade with KÁT licenses. Distributor licensees were required to expand their network for free up to a distance of 3 km if somebody wants to connect with a small power plant. Since Distributor licensees are not prepared for this, the upgrade needs to be done within 3 years, making the execution time of solar plants unsure. After acquiring METAR, the investor must complete the installation within 2 years. By amending the government decree in late April 2018, the METAR system was canceled by a five-day deadline, so no more application can be submitted for a solar plant at this time. As a result of the May 2018 revision of the regulation, the KÁT licenses can be traded again, if the investment is declared as a priority investment from a national economic point of view. Thanks to the inexplicable actions, The Hungarian Solar Panel Solar Collector Association is also meaningless. The organizations hope, that this is only a temporary state, they hope that the government is currently preparing out the agrarian program which was mentioned above.

The purpose of my present thesis is to provide a comprehensive knowledge of solar power plant investments, which can help people who are not familiar with the topic. to see the difficulties and challenges of setting up small power plants. I want to show an objective picture for the reader to consider whether it is worth investing in a solar power plant, which costs nearly 200 million forints (about 635000 Euro).
